GOST 19904-90 PDF

Full title and description

GOST 19904-90 — Cold-rolled steel sheets. Dimensions (Russian: Прокат листовой холоднокатаный. Сортамент). The standard defines the assortment (range) of cold‑rolled sheet and coil products, their nominal sizes, and classification by form and accuracy.

Abstract

This interstate (GOST) standard sets the dimensional assortment and classification rules for cold‑rolled flat steel products produced as sheets and coils. It specifies the range of thicknesses and widths covered, permissible forms, and references the relevant measurement and tolerance practices used in production and acceptance.

Scope

Applies to cold‑rolled sheet steel of nominal widths 500 mm and above, manufactured as flat sheets and as coils. Typical thickness ranges covered by the standard are: sheets 0.35 mm to 5.00 mm, coils 0.35 mm to 3.50 mm. The standard defines the standard sizes offered, while allowing by agreement with the customer non‑standard sizes where required.

Key topics and requirements

• Assortment (range) of cold‑rolled sheet and coil dimensions (thickness, width, sheet length where regulated).
• Classification by manufacturing accuracy (thickness accuracy classes), width accuracy classes, and length accuracy classes for sheets and coils.
• Flatness (surface) categories and tolerances for sheet products.
• Permitted deviations and measurement reference methods for dimensional control.
• Provisions for agreeing non‑standard sizes or tolerances between supplier and purchaser.
• Normative references and relationship to earlier standard GOST 19904-74 and related measurement standards.

Typical use and users

This standard is used by steel mills, metal service centers, fabricators, purchasers and quality departments involved in production, procurement and inspection of cold‑rolled sheet and coil. It supports product specification, acceptance testing, commercial offers, and engineering design where defined sheet dimensions and tolerances are required.
